“…12,13 From the air-dried tubers of V. arenaria, 7 already known ent-pimaradienes, namely, ent-pimara-8 (14),15dien-19-oic acid (1), 14,15 7-keto-ent-pimara-8 (14),15dien-19-oic acid (2), 14 ent-8 (14),15-pimaradien-3β-ol (3), 16 ent-8 (14),15-pimaradiene-3β, 19-diol (4), 17 ent-15pimarene-8β, 19-diol (5), 15 and ent-pimara-8 (14),15diene-3β,11α-diol (6), 7β-hydroxy-ent-pimara-8- (14), 15-dien-19-oic acid (7) 14 (Figure 1 and Table S1) were isolated and their taxonomic significance discussed to better classify the plant in the Viguiera species. 12,13 From the air-dried tubers of V. arenaria, 7 already known ent-pimaradienes, namely, ent-pimara-8 (14),15dien-19-oic acid (1), 14,15 7-keto-ent-pimara-8 (14),15dien-19-oic acid (2), 14 ent-8 (14),15-pimaradien-3β-ol (3), 16 ent-8 (14),15-pimaradiene-3β, 19-diol (4), 17 ent-15pimarene-8β, 19-diol (5), 15 and ent-pimara-8 (14),15diene-3β,11α-diol (6), 7β-hydroxy-ent-pimara-8- (14), 15-dien-19-oic acid (7) 14 (Figure 1 and Table S1) were isolated and their taxonomic significance discussed to better classify the plant in the Viguiera species.…”

“…13 Pimaradiendiol 5 was previously isolated together with several already known higher plant sesquiterpenoids along with 4 ent-pimarane-type. The relative stereochemistry of 2 and 6 and its diasteromer was determined by comparison of their NMR data with those of 1 and also by chemical correlation 14,16 and by ROESY experiment. Being a new entpimaranediol, 5 was named (−)-thermarol and characterized by spectroscopic and chemical methods.…”

“…Algumas espécies de Erythroxylum apresentam potencial farmacológico, uma vez que podem fornecer alcalóides, terpenóides e flavonóides e serem utilizadas na medicina (Ansell et al 1993;Inigo & Pomilio 1985). Erythroxylum vacciniifolium Mart., conhecido popularmente por "catuaba", é usado como estimulante do sistema nervoso central e apresenta propriedades afrodisíacas (Fonseca 1922).…”

“…A partir do estudo fitoquímico realizado com diferentes espécies do gênero Erythroxylum foram isolados vários metabólitos secundários como flavonóides e alcalóides, bem como taninos, terpenos e fenilpropanóides que apresentam atividades antioxidantes, anticancerígenas, atividade anti-inflamatória dentre outras (Ansel et al, 1993(Ansel et al, , 2003. Diversas espécies desse gênero possuem propriedades medicinais, como a popular coca (E. coca Lamk.…”
